Under actual cellular conditions, how many strongly exergonic reactions take place in glycolysis?
Fisher Esterification lab. 1. What can happen if the water produced in the reaction is not removed, and the same conditions of reflux and temperature continue? 2. Complete the following table by writing the missing names: 3. Consider the start of the reaction (time 0) when all the reagents necessary to carry out the esterification have been mixed. a. What signals of the corresponding IR spectrum of that initial reagent mixture should be observed to change significantly when the reaction...
1- Though aldol reactions work under acidic conditions, the reaction of acetophenone and piperonal works better under basic conditions. Why? 2- The aldol product is drawn as he E isomer. How can you tell whether your product was E or Z
Ethers can be formed under acidic or basic conditions. What are the limitation of forming an ether from an alcohol under acidic conditions? I. Asymmetrical ethers cannot be formed exclusively under acidic conditions II. Rearrangement in the carbon skeletal backbone is possible under acidic conditions, III. Ethers in which the carbon bound to oxygen is 3° are not possible. IV. Intramolecular cyclization reactions are not possible under acidic conditions.
Which of the following pairs CANNOT form condensation polymers given favorable esterification conditions? (Draw out the structures on scrap paper if uncertain) A) Terephthalic acid AND 1.2-ethanediol (Terephthalic acid is benzene-1, 4-dicarboxy lie acid) B) Pentanoic acid AND tras-1, 4-cyclohexanediol C) Terephthalic acid AND 1, 4-butanediol D) Lactic acid (a.k.a. 2-hydroxypropanoic acid)
